But in the modern presidency, it shouldn't be about the insecurities of one man. He should have people there to advise him to SHUT THE **** UP.
Insecurities? What you see as insecurities others see as having the courage to speak ones mind and not back down when attacked, it's a hallmark of populism and Trump is playing it pretty well. IMHO it's one of the mechanisms he has utilized effectively to befuddle the Democrats, he puts out so many targets that they don't know which one to shoot at so they're stuck singing the same old tired tunes (racism! sexism! class warfare! yada, yada...) which haven't been working.

Being a populist and being intelligent & articulate & mature do not have to be mutually exclusive.
No one said they were mutually exclusive; you missed the point entirely, the hallmark I was referring to was the tendency to speak directly to the citizenry in language that appeals to their current emotional state, the citizenry is at present angry and defiant in their attitudes toward the federal government, Trumps rhetoric reflects that very effectively, that's a principle reason that he won the election.
Trump presents the highest possible risk for populists: That his personal attributes will reflect negatively on his ideology. He brings the potential to destroy it just as easily as represent it. He's the ultimate high wire act.
.
Populists don't have any ideology, it's a direct appeal to the interests and emotions of the common citizenry and as such only works when the populist leader adopts language and mannerisms that mimic those of the masses, it's a "he's one of us" gambit not a "he shares my philosophy" one.
What you seem to be suggesting is that Trump abandon that and start speaking in Washingtonese and behaving as the much maligned, self anointed aristocracy in Washington behaves, that runs counter to everything he's been saying and doing up to now.
